Isuzu Repair: Water in oil, radiator cap, head gasket

Question
On a 96 Hombre, I'm getting water in the crankcase. I pretty much know the three areas where the problem could be. I heard about a product called Thermal Gasket.Was told it will seek out over heated hot spots and seal them. Warped head, head gasket and cracked block were some of the the problems they claim it will seal up. Ever heard of it? Not real sure the name is exactly correct. Thanks, Gary

Answer
Well if you have any of the three I would recommend a new engine or selling the vehicle Gary. There is no such thing as "miracle" in a bottle. The best thing it could do is clog up your radiator and heater core and ruin them as well. I have seen it happen a hundred times. Sorry I am just being honest with you. To see if you have any of the three pop  the radiator cap off when coolant is cool. Start vehicle and wait until the coolant drops. If you see any bubbling or it foaming really bad or looks grayish or like a milkshake. Then there is your answer.
